5 Advantages and Disadvantages of SQL | Limitations & Benefits of SQL

Structured Query Language (SQL) is a domain specific language used for establishing communication with the database. The data is allowed to manage and manipulate. i.e. inserting new data, updating or deleting existing data. 

Currently, major relational database systems like Oracle, MySQL, PostgreSQL, MS access adopt SQL as their standard database language. Without SQL, it is not possible to perform CRUD operations. 

Al though SQL is the popular programming language for web developers and data scientists, it aren't flawless. There are few drawbacks of using SQL for your developing projects. For this reason, you must analyze the pros and cons of SQL.

In this article, I will be covering about 5 Advantages and Disadvantages of SQL | Limitations & Benefits of SQL. From this post, you will know the pros and cons of SQL.

Let's get started,

Advantages of SQL

1. Speed

SQL is remarkable in terms of speed. For an example, it makes you to gather data from the database very quickly. Even other operations involving database can be performed in no time.

2. Versatility

Another important feature of SQL is the versatility it offers. Regardless of any platform or device, it can be used according to the requirement. Moreover, it has the capability to be combined with an application.

3. Technical Expertise

SQL comes with simple syntax. The rules are very simple which makes it easy to learn. Even for beginners without a background in coding. For an example, the database system requires few number of codes for the management and data retrieval process. 

4. Data Integrity

The relational database tables used in SQL is ACID compliance due to its structured nature. From this you can ensure maximum data integrity by making sure all the tables are in sync. At the same time, the accuracy of the transaction is also not compromised. 

5. Community Support

SQL is one of the most widely used programming languages around the world. Therefore, it is backed through a strong community who are willing to share their knowledge. In this way, developers can ensure there is answers for whatever the problem they encounter. 

Other than that, this makes it possible for programmers to collaborate and increase their skills.

Disadvantages of SQL

1. Cost

Another drawback of SQL is its operating cost. Standard cost of a SQL server is approximately $1400 per year. This is one of the reasons why vendors are less interested in SQL.

2. Complexity

Even though SQL does not come with any complex coding, still the interface adds more complexity. Many users complaint of accessing it. 

3. Control

Developers in SQL are not provided with full control regards to the database. The database contains hidden rules. 

4. Modifications

Modifications in SQL database scheme is difficult as well as highly resource intensive since the scheme is already defined. Thus, the modifications needs to be implemented in the development stage with the planning started before the production. Otherwise, the database doesn't allow you to modify both in terms of volume and data.

5. Expandability

Under normal conditions, only vertical type of scaling is allowed in SQL databases. This is considered to be expensive because of the hardware expansion. 

At the same time, scaling horizontally with partitioning is also harder, time consuming and resource intensive. Hence, programmers must keep in mind that scaling on SQL database increases complexity through means of coding and professionalism.
